Erta Ale erupting within the Danakil Depression Mount Ayalu, the westernmost and older of two volcanoes at the southern end of the Danakil Depression. The Danakil Depression is the northern part of the Afar Triangle or Afar Depression in Ethiopia and Eritrea, [1] [2] a geological depression that has resulted from the divergence of three tectonic plates in the Horn of Africa.
It has been argued that the current Ethiopian plateau is a result of the most recent uplift of 500 metres (1,600 ft) estimated to be an Oligocene–early Miocene event. But the most accepted argument of the plateau is the result of the Paleogene flood-basalts. The uplift associated with both domes has resulted in major structural features due ...
The Depression overlaps the borders of Eritrea, Djibouti and the entire Afar Region of Ethiopia; and it contains the lowest point in Africa, Lake Assal, Djibouti, at 155 m (509 ft) below sea level. The Awash River is the main waterflow into the region, but it runs dry during the annual dry season, and ends as a chain of saline lakes .
A third major plantion surface and uniformity formed in the following a tectonic event in the Early Cretaceous that tilted carbonates in the Tigray and Dire Dawa-Harar areas. [1] On top of this surface lies a series a fluvial sediments. [1] Depositions of marine sediments continued in eastern Ethiopia's Ogaden basin until the Eocene. [1]
This article describes techniques; for a history of the movement of tectonic plates, see Geological history of Earth.. Plate reconstruction is the process of reconstructing the positions of tectonic plates relative to each other (relative motion) or to other reference frames, such as the Earth's magnetic field or groups of hotspots, in the geological past.
The Blue Nile Basin is a major geological structure in the northwestern Ethiopian Plateau formed in the Mesozoic Era during a period of crustal extension associated with the break-up of Gondwana, and filled with sedimentary deposits. The modern Blue Nile river cuts across part of the sedimentary basin. [1]
The Danakil Desert (or Afar Desert) is a desert in northeast Ethiopia, southern Eritrea, and northwestern Djibouti.Situated in the Afar Triangle, it stretches across 136,956 square kilometres (52,879 sq mi) [citation needed] of arid terrain.
The Danakil Alps are a highland region in Ethiopia and Eritrea with peaks over 1000 metres in height and a width varying between 40 and 70 kilometres. [1] The area is known in the Afar language as Arrata. The alps lie along the southern Red Sea [2] to the east of the Danakil Depression [3] and separate it from the sea. [4]
